当设计建筑物轻型围护结构时,墙体的防潮保护问题具有很大的意义。当前的施工中,一般采用涂抹、粘贴、镶面和喷漆的防潮层。上述防潮层除优点外,均有一定的缺点,并且,这些防潮层的共同问题是对于机械损伤特别敏感。本文提出的墙体防潮保护方法,则避免了上述防潮层的缺点;并且该方法在使用中是经济可靠的。本方法的实质在于,在平整的混凝土和钢筋混凝土表面,局部加热到80～90℃,同时,用石蜡锭摩擦表面,至板面均匀变暗为止。混凝土板面呈现暗淡状态,系由于石蜡熔化,渗入混凝土表面层所有缝隙和开口孔隙深度达2～3毫米的结果。
When designing buildings with light containment structures, the issue of moisture protection of the walls is of great significance. In the current construction, damp-proof layers such as painting, pasting, veneering, and painting are generally used. In addition to the advantages described above, the moisture-proof layer has certain disadvantages, and the common problem of these moisture-proof layers is that they are particularly sensitive to mechanical damage. The wall moisture protection method proposed in this paper avoids the disadvantages of the above-mentioned damp proof layer; and this method is economical and reliable in use. The essence of the method lies in that, on the surface of smooth concrete and reinforced concrete, local heating is performed to 80-90°C. At the same time, the surface is rubbed with a paraffin ingot until the surface of the board is uniformly darkened. The surface of the concrete slab is in a dim state due to the melting of the paraffin wax and the penetration of all the gaps in the concrete surface layer and the open pore depth to a depth of 2 to 3 mm.
